A scale factor of 2 means everything is shown in half the size of the original.
The scale factor of 0.8 represents a reduction in size by a factor of 0.8. This means that the new size is 80% of the original size. In mathematical terms, the scale factor of 0.8 can be represented as a fraction as 4/5 or a percentage as 80%.
With a scale factor of 1, the image is exactly the same size as the original object.
If the scale factor between two shapes is 1, the shapes are congruent.
it is called a outter figure shape
A scale factor of 2.
The scale factor that doubles the size of a figure is 2. When a figure is enlarged by a scale factor of 2, all its dimensions—such as length, width, and height—are multiplied by 2, resulting in a figure that has four times the area and eight times the volume of the original.
A scale factor of one means that there is no change in size.
A dilation with a scale factor of 0.5 reduces the size of the figure to half its original dimensions, resulting in a smaller figure. In contrast, a dilation with a scale factor of 2 enlarges the figure to twice its original dimensions, creating a larger figure. Therefore, the two dilations produce figures that are similar in shape but differ significantly in size, with the scale factor of 2 yielding a figure that is four times the area of the figure dilated by 0.5.

A transformation determined by a center point and a scale factor is known as a dilation. In this transformation, all points in a geometric figure are moved away from or toward the center point by a factor of the scale. If the scale factor is greater than 1, the figure enlarges; if it is between 0 and 1, the figure shrinks. This transformation preserves the shape of the figure but alters its size.
No, a scale factor of a dilation is not always between 0 and 1. A scale factor can be greater than 1, which results in enlargement, or it can be between 0 and 1, leading to a reduction. Additionally, a negative scale factor can invert the figure. Thus, the scale factor can vary widely, affecting the size and orientation of the figure being dilated.

The two key characteristics of a dilation are the center of dilation and the scale factor. The center of dilation is a fixed point in the plane from which all other points are expanded or contracted. The scale factor determines how much the figure is enlarged or reduced; a scale factor greater than one enlarges the figure, while a scale factor between zero and one reduces it. Dilation preserves the shape of the figure but changes its size.
A similarity transformation uses a scale factor to enlarge or reduce the size of a figure while preserving its shape. It includes transformations such as dilation and similarity.
